Can't connect to localhost on Raspberry

Solved

Hello,

I install Blynk yesterday on my Raspberry Pi 3. On my Pi, i have the server and the project. I want to connect the project to the server in localhost, as I made few mounth ago (Blynk 0.5.0). But, with the same technic, it didn’t work :

[2] Connecting to localhost:80
[3] Can't connect to localhost
[2009] Login timeout

I don’t remember if I did something special the first time.
This is the code, I use the default one with the server change.


#define BLYNK_PRINT stdout
#ifdef RASPBERRY
  #include <BlynkApiWiringPi.h>
#else
  #include <BlynkApiLinux.h>
#endif
#include <BlynkSocket.h>
#include <BlynkOptionsParser.h>

static BlynkTransportSocket _blynkTransport;
BlynkSocket Blynk(_blynkTransport);

static const char *auth, *serv;
static uint16_t port;

#include <BlynkWidgets.h>

BLYNK_WRITE(V1)
{
    printf("Got a value: %s\n", param[0].asStr());
}

void setup()
{
    Blynk.begin(auth, "localhost");
}

void loop()
{
    Blynk.run();
}


int main(int argc, char* argv[])
{
    parse_options(argc, argv, auth, serv, port);

    setup();
    while(true) {
        loop();
    }

    return 0;
}

I hope someone can help me.
Thanks !

Try just using the actual IP of the RPi (and port 8080)
